Unverified Database Matrix

Following is a table of the database and JDBC driver versions that have been reported
to work with OpenJPA by the community but have not been verified by the development
team. In some cases this is a question of availability since the developers may not
be able to obtain a license to test, or have experience configuring these databases.
For the list of databases that have been fully tested against this release, please
refer to the Verified Database Matrix section.
